A letter report issued by the Government Accountability Office with an abstract that begins "Since 1996, the Veterans Benefit Administration (VBA) has been working on an initiative to replace its aging system for paying compensation and pension benefits. In 2005, concerned about the slow pace of development, VBA contracted with the Software Engineering Institute (SEI) for an independent evaluation of the project, known as the Veterans Service Network (VETSNET). SEI advised VBA to continue working on the project at a reduced pace while addressing management and organization weaknesses that it determined had hampered the project's progress. GAO was requested to determine to what extent the VETSNET project has followed the course of action recommended by SEI and describe the project's current status. To perform its review, GAO analyzed project documentation, conducted site visits, and interviewed key program officials."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) Privacy Office was established with the appointment of the first Chief Privacy Officer in April 2003, as required by the Homeland Security Act of 2002. The Privacy Office's major responsibilities include: (1) reviewing and approving privacy impact assessments (PIA)--analyses of how personal information is managed in a federal system, (2) integrating privacy considerations into DHS decision making, (3) ensuring compliance with the Privacy Act of 1974, and (4) preparing and issuing annual reports and reports on key privacy concerns. GAO's objective was to examine progress made by the Privacy Office in carrying out its statutory responsibilities. GAO did this by comparing statutory requirements with Privacy Office processes, documents, and activities."

A letter report issued by the Government Accountability Office with an abstract that begins "The success of the 2010 Census depends, in part, upon the U.S. Census Bureau's (Bureau) ability to recruit, hire, and train over half a million temporary workers at peak. Under the Comptroller General's authority, GAO reviewed the extent that the Bureau's (1) recruiting and hiring processes for these staff are consistent with selected human capital principles and (2) training delivery and content take into account known challenges. To answer these questions, GAO analyzed relevant reports and past recommendations to select principles for evaluating these activities, reviewed related Bureau documents, observed the 2006 Census Test in South Dakota and Texas, and interviewed Bureau officials."

Correspondence issued by the Government Accountability Office with an abstract that begins "This report responds to certain requirements of the Haitian Refugee Immigration Fairness Act (HRIFA) of 1998 that authorized certain Haitian nationals and their dependents to apply to adjust their status to lawful permanent residence. Section 902 (k) of the act requires the Comptroller General to report every 6 months on the number of Haitian nationals who have applied and been approved to adjust their status to lawful permanent residence. The reports are to contain a breakdown of the number of Haitians who applied and the number who were approved as asylum applicants, parolees, children without parents, orphaned children, or abandoned children; or as the eligible dependents of these applicants, including spouses, children, and unmarried sons or daughters. Reports are to be provided until all applications have been finally adjudicated. This is GAO's sixteenth report."

A letter report issued by the Government Accountability Office with an abstract that begins "At a time when U.S. military forces and their equipment are in high demand, effective management of the Department of Defense's (DOD) inventory is critical to ensure that the warfighter has the right items at the right time. The Air Force is the largest contributor to DOD's total on-hand inventory on the basis of inventory value. Under the statutory authority of the Comptroller General to conduct evaluations on his own initiative, GAO determined the extent to which (1) the Air Force's on-order and on-hand inventory reflect the amount of inventory needed to support required inventory levels from fiscal years 2002 through 2005, and (2) the Air Force had shortages in its inventory needed to support required levels during this period. To address these objectives GAO analyzed Air Force secondary inventory data (spare parts such as engines and guided missiles) from fiscal years 2002 through 2005."

A letter report issued by the Government Accountability Office with an abstract that begins "The National Polar-orbiting Operational Environmental Satellite System (NPOESS) is a tri-agency acquisition--managed by the Departments of Commerce and Defense and the National Aeronautics and Space Administration--which experienced escalating costs, schedule delays, and technical difficulties. These factors led to a June 2006 decision to restructure the program thereby decreasing the program's complexity, increasing its estimated cost to $12.5 billion, and delaying the first two satellites by 3 to 5 years. GAO was asked to (1) assess progress in restructuring the acquisition, (2) evaluate progress in establishing an effective management structure, (3) assess the reliability of the cost and schedule estimate, and (4) identify the status and key risks facing the program's major segments. To do so, GAO analyzed program and contractor data, attended program reviews, and interviewed program officials"

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) relies extensively on information technology (IT) to carry out its mission. For fiscal year 2008, DHS requested about $4 billion--the third largest planned IT expenditure among federal departments. Given the size and significance of DHS's IT investments, GAO's objectives were to determine whether DHS (1) has established the management structure and associated policies and procedures needed to effectively manage these investments and (2) is implementing key practices needed to effectively control them. GAO used its IT Investment Management (ITIM) framework and associated methodology to address these objectives, focusing on the framework's stages related to the investment management provisions of the Clinger-Cohen Act."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) fiscal year 2006 appropriations act provided $40.15 million for the Immigration and Customs Enforcement's (ICE) program to modernize its information technology (IT) infrastructure. As mandated by the appropriations act, the department is to develop and submit for approval an expenditure plan for the program, referred to as "Atlas," that satisfies certain legislative conditions, including a review by GAO. In performing its review of the Atlas plan, GAO (1) determined whether the plan satisfies certain legislative conditions and (2) provided other observations about the plan and management of the program. To do this, GAO analyzed the fiscal year 2006 Atlas expenditure plan and supporting documents against the legislative conditions, federal requirements, and related best practices. GAO also interviewed relevant DHS officials."

Spatially resolved measurements of deuterium Balmer and Paschen line emission have been performed in the divertor region of the National Spherical Torus Experiment using a commercial 0.5 m Czerny-Turner spectrometer. While the Balmer emission lines, Balmer and Paschen continua in the ultraviolet and visible regions have been extensively used for tokamak divertor plasma temperature and density measurements, the diagnostic potential of infrared Paschen lines has been largely overlooked. We analyze Stark broadening of the lines corresponding to 2-n and 3-m transitions with principle quantum numbers n = 7-12 and m = 10-12 using recent Model Microfield Method calculations (C. Stehle and R. Hutcheon, Astron. Astrophys. Supl. Ser. 140, 93 (1999)). Densities in the range (5-50) x 10{sup 19} m{sup -3} are obtained in the recombining inner divertor plasma in 2-6 MW NBI H-mode discharges. The measured Paschen line profiles show good sensitivity to Stark effects, and low sensitivity to instrumental and Doppler broadening. The lines are situated in the near-infrared wavelength domain, where optical signal extraction schemes for harsh nuclear environments are practically realizable, and where a recombining divertor plasma is optically thin. These properties make them an attractive recombining divertor density diagnostic for a burning plasma experiment.

High spatial-resolution secondaryion microprobespectrometry, synchrotron radiation Fourier-transform infraredspectroscopy and polyacrylamide gel analysis demonstrate the intimateassociation of proteins with spheroidal aggregates of biogenic zincsulfide nanocrystals, an example of extracellular biomineralization.Experiments involving synthetic ZnS nanoparticles and representativeamino acids indicate a driving role for cysteine in rapid nanoparticleaggregation. These findings suggest that microbially-derivedextracellular proteins can limit dispersal of nanoparticulatemetal-bearing phases, such as the mineral products of bioremediation,that may otherwise be transported away from their source by subsurfacefluid flow.

The fascinating shapes and hierarchical designs of biomineralized structures are an inspiration to materials scientists because of the potential they suggest for biomolecular control over materials synthesis. Conversely, the failure to prevent or limit tissue mineralization in the vascular, skeletal, and urinary systems is a common source of disease. Understanding the mechanisms by which organisms direct or limit crystallization has long been a central challenge to the biomineralization community. One prevailing view is that mineral-associated macromolecules are responsible for either inhibiting crystallization or initiating and stabilizing non-equilibrium crystal polymorphs and morphologies through interactions between anionic moieties and cations in solution or at mineralizing surfaces. In particular, biomolecules that present carboxyl groups to the growing crystal have been implicated as primary modulators of growth. Here we review the results from a combination of in situ atomic force microscopy (AFM) and molecular modeling (MM) studies to investigate the effect of specific interactions between carboxylate-rich biomolecules and atomic steps on crystal surfaces during the growth of carbonates, oxalates and phosphates of calcium. Specifically, we how the growth kinetics and morphology depend on the concentration of additives that include citrate, simple amino acids, synthetic Asp-rich polypeptides, and naturally occurring Asp-rich proteins found in both …

We have built a velocity imaging (VMI) spectrometer optimized for angle-resolved photoionization experiments with synchrotron radiation (SR) in the VUV and soft X-tay range. The spectrometer is equiped with four electrostatic lenses that focus the charged photoionization products onto a position-sensitive multi-hit delay-line anode. The use of two additional electrostatic lens elements as compared to the standard design of Eppink and Parker [T.J.B. Eppink and D.H. Parker, Rev. Sci. Instrum. 68 (1997) 3477]provides better focusing of an extended interaction region, which is crucial for most SR applications. Furthermore, the apparatus is equipped with a second micro-channel plate detector opposite to the VMI spectrometer, enabling electron-ion coincidence experiments and thereby mass-resolved ion spectroscopy independent of the time structure of the synchrotron radiation. First results for the photofragmentation of CO2 molecules are presented.

Traditionally, the susceptibility of Alloy 22 (N06022) to suffer crevice corrosion has been measured using the Cyclic Potentiodynamic Polarization (CPP) technique (ASTM G 61). When the alloy is not very susceptible to crevice corrosion, the values of repassivation potential obtained using the CPP technique are not highly reproducible. To circumvent the large uncertainty in the values of the repassivation potential by the CPP method, the repassivation potential of Alloy 22 may be measured using a slower method that combines sequentially potentiodynamic, galvanostatic and potentiostatic treatments (this method is called the Tsujikawa-Hisamatsu Electrochemical or THE method). In the THE method the anodic charge is applied to the specimen in a more controlled manner, which avoids driving the alloy to transpassivity and therefore results in more reproducible repassivation potential values. Results using THE method under various testing conditions are presented. A new standard has been prepared for ASTM balloting for the THE method. The round robin matrix results are also discussed.

An extensive set of covariances for neutron cross sections in the energy range 5 keV-20 MeV has been developed to provide initial, low-fidelity but consistent uncertainty data for nuclear criticality safety applications. The methodology for the determination of such covariances combines the nuclear reaction model code EMPIRE, which calculates sensitivity to nuclear reaction model parameters, and the Bayesian code KALMAN to propagate uncertainty of the model parameters to cross sections. Taking into account the large scale of the project (219 fission products), only partial reference to experimental data has been made. Therefore, the covariances are, to a large extent, derived from the perturbation of several critical model parameters selected through the sensitivity analysis. These parameters define optical potential, level densities and pre-equilibrium emission. This work represents the first attempt ever to generate nuclear data covariances on such a scale.
